Beschreibung
Zusammenfassung:	The utility model discloses an auxiliary device for hoisting connection of a prefabricated pipeline, which comprises an outer arc component coaxially arranged behind the prefabricated pipeline, a plurality of U-shaped clamping groove components are arranged on the circumference of the outer arc component, and the outer arc component is positioned at the tail parts of the U-shaped clamping groove components; an inner arc component is coaxially arranged between the outer arc component and the prefabricated pipeline, the inner arc component is located in clamping grooves of the U-shaped clamping groove components, and the diameter of the inner arc component is matched with the diameter of the prefabricated pipeline. And a propelling device is arranged between the outer arc component and the inner arc component in the clamping groove of the U-shaped clamping groove component. Hoisting and butt joint of the prefabricated pipeline are separately operated, the three U-shaped clamping groove components on the outer a
